AP's chief photographer in Asia, David Guttenfelder, has been in North Korea for the past week. It's not his first time—it's his 20th, dating back to 2000—and it's not the first time he's been there with his phone, either. But it is the first time he's taking geotagged Instagram photos. He writes on his blog:

Fast forward to this week when North Korea's mobile phone service provider Koryolink announced that all foreigners visiting North Korea will be allowed to bring in their phones and connect to the internet on the DPRK's 3G network.

It's a powerful way to connect directly with the outside world from one of the most isolated countries on earth. The window on to North Korea has been opened a small crack.

Meanwhile for all North Koreans, who will not be allowed access to the same service, the window remains firmly shut.
